Reports cases when an equality check should be used instead of the elvis operator.
<p><b>Example:</b></p>
<pre><code>
fun check(a: Boolean? == null) {
    if (a ?: false) throw IllegalStateException()
}
</code></pre>
<p>After the quick-fix is applied:</p>
<pre><code>
fun check(a: Boolean? == null) {
    if (a == true) throw IllegalStateException()
}
</code></pre>
